A Low-Cost Very Large Scale Integration Architecture For Idct With Sharing Techniques
S. Shunmugapriya, M. Saravanan · 2013
Abstract:- The intercommunications between the video devices using different standards are so much inconvenient, thus video codec suppor ting multiple standards are more useful and more attractive. In this brief, a low cost very large scale integration (VLSI) architecture is designed for multistandard inverse Discrete Cosine transform. It is used in multistandard decoder of MPEG-2, MPEG-4 ASP, and VC-1.Two circuit share strategies, factor share (FS) an adder share (AS) are applied to the inverse transform architecture for saving its circuit resource. Pipelined stages are used in this Multistandard inverse transform to increase the operational speed. Keywords:- Hardware Share, multiple inverse transform, Video decoding,factor share,adder share. 1.
